Wulfhere

Wulfhere (died May 878) was a West Saxon ealdorman who sided with the Danes at the Battle of Edington in 878, during which he was killed.

Biography
Wulfhere was born in Wessex to an Anglo-Saxon family, and he became one of King Alfred the Great's ealdormen. In 878, Alfred sent Wulfhere and Odda of Devon to march towards the Severn River to face Ubbe Ragnarrsson as Alfred marched south to face Guthrum, but Wulfhere objected to this strategy, believing that the West Saxons should march as one. Wulfhere later betrayed King Alfred during a Witenagemot session, leaving early to free his Danish hostages (including Ragnar Ragnarsson) and pledge loyalty to Guthrum as his army attacked the royal estate at Chippenham. He went on to fight alongside the Danes at the Battle of Edington, during which he was slain by the West Saxon army.
